Rock wool board as a fireproof and insulation material, has good compressive and tensile strength, and the properties of heat insulation, fire prevention, moisture resistance, sound absorption. It is mainly applied to the roof & wall thermal insulation systems. Its Class A non-combustible fire prevention grade can keep the system structure stable in case of fire.

1.Rockwool is made of natural rock and is a Class A non-combustible fireproof material. Its melting temperature is over 1000ºC, which can effectively slow down the spread of fire.
2.The thermal conductivity is low and the thermal insulation effect is significant.
3.Greatly reducing the reflection and propagation of sound waves and providing a beneficial environment without interference for work and life.
4.The open porous fiber structure makes rockwool have excellent air permeability and moisture-drying function, which allows water vapor to pass freely, effectively reducing condensation and building mildew.
5.The rock wool for external wall insulation, high-strength rock wool board for roofs and composite board with rock wool have high tensile strength and compression strength, which can effectively resist the alternating effects of positive and negative wind pressures and have strong impact resistance.
6.Rock wool is frost-resistant, freeze-thaw resistant, and UV-resistant. It does not produce thermal expansion andcontraction due to temperature differences in the four seasons. It can be used in extreme climates without being affected by other combined materials.
7.Water-repellent and moisture proof.
8.The energy saved by rock wool in use is more than 100 times the energy consumed in its production, transportation and recycling.
9.Safe and environmental protection.
10.Easy to carry and cut. It can be completed with a scissors.
